To all whom it may concern:

Be it known that l, Gnonen J. KELLEY, a citizen of the United States, residin at Attleboro, in the county of Bristol and tate of Massachusetts, have invented certain new ability for use with a single hand; capacity for continuous and uninterrupted discharge, simplicity and inexpensiveness.

To the above ends essentially my invention consists in such novel parts and combination of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification and in which like reference letters indicate like parts throughout the views, Figure 1 is a side elevation of my novel atomizer Fig. 2, a central longitudinal section of the same, Fig. 3, an enlarged section of the lower portion of the piston, Fig. 4, an enlarged section of the valve block, and Fig. 5, a bottom plan view of the flap.

My device comprises a casing 5 of an outline adapted to be readily grasped by the hand having in its rear portion a piston chamber 6 closed at its upper end by acap 7 having a threaded connection 10 with the casing and provided with an air inlet 11 and acentral opening 12. An exteriorly threadedblock 13 is provided with an external annular channel 14 which is fixed in the threaded lower end of the cylinder chamber. It has acentral cavity 16 in its upper portion permitting movementoi aflexible flap 17 integral with awasher 18 resting upon the top of the block and superimposed upon which is adisk 19 provided with acentral opening 20. Thecavity 16 is an enlargement of apassage 21 extending into the channel 14. From this channel is anotherchannel 22 leading through the casing wall to anair storage chamber 23 located in the casing adjacent the cylinder chamber. Slidable in theopening 12 in thecap 7 is apiston rod 24 provided with ahandle 25 in the form of a milled disk, and provided at its lower end with a piston. In the present instance the piston comprises adisk 27 seated upon a reducedportion 28 of the rod. The latter is exteriorly threaded at itsend 30 to engage an interiorly threadedcap 32 whose open end abuts against the disk. The closedend 34 of the cap is provided withopenings 36 and supports aball 38 in a chamber orcavity 39 in the end of therod 24. From this cavity extends apassage 40 opening into the chamber 6 which passage is of less diameter than that of the ball.

Abase portion 41 of the casing is forwardly extended as at l2 and provided with aconcave seat 43 adapted to receive the lower end of aflask 45 preferably of glass, having a reducedneck portion 46 provided with external threads 4:7. The flask has also a lateral upwardly directedneck 49 provided with threads 50 engaging an interiorly threadedcap 52. Anextension piece 54 is integral with the casing forming a part thereof or connected to aprojection 56 of the latter by acollar 58 whose flange 59 is seated in anannular groove 60 upon the projection and whose interior is threaded as at 61 to engage an exteriorly threadedprojection 62 upon thepiece 54 abutting against theprojectio'n 56. Theprojections 56 and 62 have respectivelypassages 63 and 64 registering with each other and leading from thechamber 23 to the interior of theflask 45. Thepiece 54 has its lower portion undercut to receive theneck 46 and is provided withinternal threads 65 to engage thethreads 47. Upon the top of thenecks 46 and 49 respectively aregaskets 66 and 67 if desired. A

vertically disposed tube 69 extends con--flask 45 and is fixed at its upper end in thepiece 54 in any convenient manner. Its lower end is open as at 70 adjacent the bottom of the flask, while a perforation 71 in the tube is located near the top of the flask. Thechamber 72 of the flask is partially filled withliquid 73. The removable orauxiliary portion 54 of the casing has a horizontal passage 75 disposed at right angles to avertical passage 76 extending trom the tube 69 to the center of the horizontal passage. In one end of the latter passage is a needle valve comprising amilled head 77 and ashank 78 provided with threads engaging threads 80 in the casing, and having aneedle point 81 adapted to cooperate with an annular seat 82 of the casing. -Located in the horizontal passage adjacent the opposite side of the seat 82 is the threaded end 84: of a horizontal tube 85 provided with a conicalouter end 86 and an external shoulder orhead 87 loosely engaged by the flange 88 of union or sleeve 89 provided with internal threads 90 engaging centrically of the -40, and 36.

threads 91 upon the end of a curvedhard rubber tube 92 loosely surrounding thecomcal portion 86. The union 89 may be united with thetube 92 in any other convenient manner. Thetube 92 is provided upon its outer end with a spherical projection 85 which registers in aspherical cavity 97 in the end 01 another curvedtubular section 98 upon whose end is fixed a cap 99 provided with spraying perforations. Since thetube 92 is swiveled upon the tube 85; and thetube 98 is swiveled upon thetube 92 it will be noted that thedischarge nozzle 100 is capable of a variety of radial adjustments, some of which are shown in broken lines in Fig. 2.

The operation of my spraying device is as follows: The storage chamber is first filled with air. This is efi'ected by operating the air pump as follows. The piston forces the air through thepassages 20, 16, 21, and 22 into thechamber 23 by its downward stroke which opens also theflap 17. During the descent of the piston theball 38 moves upwardly and closes theair passage 40. During the upward stroke of the piston the air is permitted to pass through the passages 11, After the atomizer has been thus charged the casing is grasped in the operators palm so that the thumb and torefinger may engage thehead 77 and thus control, by adjustment of thepoint 81 relatively to the seat 82, the discharge of fluid through thetubes 85, 92, and 98. The compressed air in thechamber 23 is discharged through thepassages 63 and 64 into the chamber 75 and enters the perforation 71. It also presses upon the surface of thewater 73 which rushes up through the opening and mixed with the air, is forced through the tube 69, past theneedle valve 81 and through thetubes 85, 92, and 98. The liquid is discharged as a spray through theperforated nozzle 100. The flask is replenished with liquid through theneck 49 after removal of thecap 52.

When the parts are constructed as herein shown they may be disassembled by unscrewing theunion 58; and by unscrewing thecasing section 54 from the neck of the flask.
